“…It is estimated that 90% of the world's trade in goods is carried out by sea. However, most ships use fossil fuels to meet their energy needs, resulting in the emission of pollutant gases, particulate matter, and greenhouse gases (GHG) [1] . The development of clean and renewable energy and large-scale use of port power and charging facilities are the main measures to achieve the port carbon reduction target.…”

With the development of ship electrification, the demand for energy in ports is increasing. The location and natural resources of ports also create conditions for the development of ship electrification. This paper firstly analyzes the current development status of floating solar power generation technology and offshore wind power generation technology, summarizes the obstacles facing the development of offshore power generation platforms, introduces the materials and structures that can be used for floating power generation platforms, and then introduces the port microgrid topology from three aspects of AC microgrid (AC), DC microgrid (DC) and AC/DC hybrid microgrid (AC/DC) hybrid structure, and compares the three structures. Then the existing control methods are reviewed from the perspective of port capacity planning and the application of distributed control in port energy planning is emphasized. Finally, port energy management strategies are introduced from the perspective of multiple time scales, and relevant cases are listed, and the advantages and disadvantages of management strategies under different time scales are compared. At the end of the paper, several advanced smart ports are given as examples, and the new energy used by each port and its development scale are analyzed, and the future clean and efficient ports are envisioned.

“…Moreover, all-electric ships appeared recently, with the launch of the first fully electric car ferry in Norway in 2015 [8,9]. In this kind of vessel, electrical energy can be generated by renewable sources and the use of storage systems is often considered, such as batteries [8,9], supercapacitors [10,11], and hydrogen [8]. To limit the use of fossil fuels as much as possible, the electrical supply of berthed vessels provided by the onshore grid is increasingly considered, and details of this can be found in the literature under the terms of cold-ironing [9], shore-side electricity supply [12] or shore-to-ship power [13].…”

Design, Sizing, and Energy Management of Microgrids in Harbor Areas: A Review

et al. 2020

View full text Add to dashboard Cite

Energy efficiency and low-carbon energy systems are increasingly taken into account in seaports, due to climate change challenges and the evolution of environmental regulations. Thus, technological breakthroughs must be brought to numerous systems in harbors, such as harbor cranes, seaport vehicles, or the power supply of berthed vessels. These aspects may require the establishment of a microgrid in the harbor area. Microgrids have been subjected to a wide development on the mainland and islands, mostly for domestic loads. However, these are still scarce in harbor areas. Their development in such places faces several challenges, such as high power requirements, monitoring and management of a wide range of loads, energy policy framework, etc. Moreover, the establishment of a microgrid involves a study of sizing and of energy management, to avoid prohibitive costs and to verify load requirements. This paper provides a literature survey related to the development of microgrids in seaport areas. Firstly, the main components that occur in harbor microgrids are listed, and then a review of studies dealing with sizing and energy management is proposed. Finally, from this survey, innovative concepts and barriers are listed, with an up-to-date review of microgrid development in seaports worldwide.
